As long as I can remember there is the green liquid in the bottle on Curaçao called Glacial. I once won a small bottle of Glacial at a fair in kindergarten.
Glacial was a left-over product from the process of producing Blue Curaçao. It contains a lot of alcohol but is for external use. It is good against ‘muggen’, but only for 10 minutes. I can disinfect my hands with it. There was always a bottle or more in the home I grew up in back then on Curaçao. I can now also buy Glacial in The Netherland.
